To all it may concern: Be it knownt'hat I, ALEXANDER G. BROW- NELL,-a bijtizen' of the United. States,'residing at Providence, in' the county of Providenceand Stateof Rhode Island, have invented oer: tain new and useful Improvements in Roller Bearings for Oarriage-Wheels, of v which the following is a specification, reference being had therein to theaccompanying drawings.

Like letters indicate like parts. Figure 1 is an end elevation 'of one of the ball-bearing rings 'of my-device,showing the balls mounted in the annular channel thereof. Fig. 2 is an elevation of the exterior side of said ball-bearing ring and illustrates the annular channel of the same and how the balls may be inserted in the channel. Fig. 3 is a view of said ring as'seen partly in elevation and partly in section on the diameter thereof.

Fig. 4 is a side elevation of the cage and illustrates the manner in which the rollers are mounted. Fig. 5 is acentral longitudinal secprovided the pins or journals of the rollers J.

tion of the hub of a carriage-wheel with my improved roller-bearing.

My invention relates to roller and ball bearings for the hubs of carriage-wheels; and it consists of the combination, with a carriage-.

-- wheel hub and the axle on which said hubis mounted,of a cage provided with rollers which the sides of the cage adapted to resist the endthrust friction of the wheel-hub against suit- 1 able bearing-surfaces, which balls are loosely orwagon screw-threaded at its outer end, as

B is the hub of the wheel, having the" usual.

usual spokes O. The ends of the hub Bhave caps, as shown in Fig. 5. hub, which is straight and uniform throughout, a tube or box N is inserted. A nut P, having a flange :19, engages with the screwthreaded end of the axle A.

A cage 11 is provided for the hub B, and consists of two rings'for rollers, mounted rotatably between them. Some rollers (indi- Figs. 4 and 5.

rollers J however,-proj ect slightly beyond the outer surfaces of the rings of the cage H, as

are in rolling contact with the axle, and also. with balls and a supporting-ring therefor on In the hereof the 4 cated as I) have their journals i integral therewith, while others of the rollers, preferably three in number, (indicated as J have each a central tubular here through which a journal or pin loosely passes, so that said roller J may rotate thereon. roller'Iextend through the rings of the cage H, so that their ends lie flush with the outer surface of the rings, respectively, as seen in The j'ournals'or pins of the illustrated in said figures. The rollers I J are so mounted that their peripheries extend slightly beyond the'inner circumference of the rings of the cage H, as shown.

The journals t'of the On each end of the cage H is a ball-supporting ring K. filth'ese rings have an annular channel on their outer surfaces between two annular lips or flanges l m.- The lips Z on are notched or slightly cut away, as at 'n. The ring Khas three or more sockets 0, corresponding in number, size, and position with Balls L are mounted loosely in the channelsk of the rings K, respectively. Each ball is inserted in the enlargedspace provided by the notches n, and the lips Z on confine the,

balls L within the channel It, as shown in Fig. 1.

The cage H and rings K are assembled as shown in Fig. 5, the journals of the rollers J extending into and fitting snugly the sockets o of said rings. The halls Let the inner series have their external bearing within the box N of the hub against the flange or fixed collar M of the axle A, as seen in Fig. 5, and the balls of the outer series have their external bearing against the back of the flange pofthenutP.

The rollers I and J are in contact with the tube or box N, as shown in Fig. 5, and give a vertical roller-bearing upon the axle A, while the balls L furnish a lateral or endwise bearing against the flange Maud the inner surface of the flange of the nut P. The halls L are useful to receive the end-thrust friction when the wheel is traveling on a curve, and the rollers I J furnish the bearing when or course.

ihe caps onthe outer and inner endsof the hub B serve 'toexclude the dust from theaxle, box, rollers, and bearings. v The projection of the journals of the rollers J beyond the outer surface of the rings 1C makes them useful as a fastening means to hold said rings to'the cage 11, which is accomplished by the sun 2; engagement of said journals in the .s'oekets 0 of the rings K, as

seeniin Fig. 5. v a y a I claim as a novel and useful invention and desire to. secure by Letters Patent-' In combination withawheel-hub, centrally and longitudinally bored, a tube inserted in said bore, an axle screw-threaded at its outer end and having, at a distance from the outer end nearly equal to the length of the hub,

a flange extending circumferentially there- .i

from, a nut engageable with the end of the axle and provided with a. flange, rollers mounted in rings and adapted to furnish bearings between the -hub and axle,ball-bearing rings placed externally of the rings first named and provided each with an annular channel, and balls mounted loosely in said channels and having bearings against said flanges, respectively, substantially as described.- v

In testimony whereof I aflix my signature in presence of two witnesses.
